Table API zipWithIndex

Hi to all,
is there any plan to support the equivalent of DataSetUtils.zipWithIndex as
a select expression in the Table API? is it possible to implement it as an
UDF right now?

Best,
Flavio

unfotunately..)
Thanks Timo!

Hi Flavio,

I guess you are looking for a unique identifier for rows, right? 
Currently, this is not possible in Table API. There, we only support 
UUID(). Once the Table API has been enhanced to be more interactive, we 
might support such features.

Regards,
Timo
